[arch-general] Astrometa DVB T2 stick

[Frank Zimmermann]

good afternoon,

I'm trying to get my new DVBT2 stick to work following instructions
from Arch Wiki and Linuxtv.org.

Here's the output from demsg

ERROR: Sorry - i couldn't get any working frequency/transponder
 Nothing to scan!!

The device looks to me recognised and initialised but don't get w_scan

So what am I missing?

Thanks Frank
